FIG. 1 is a diagram illustrating a method of displaying an execution result of an associated application related to an interest object, according to an exemplary embodiment.

Referring to FIG. 1(a), interest objects may be displayed on a screen of the device 1000, and a user may touch an area of the screen of the device at which one of the interest objects is displayed. The interest object may be an icon including text and an image, but one or more exemplary embodiments are not limited thereto.

Referring to FIG. 1(b), in response to a user selecting one of the interest objects displayed on the screen of the device 1000, the device 1000 may obtain metadata related to the selected interest object, and may execute one or more associated applications related to the selected interest object based on the metadata. Also, the device 1000 may display, on the screen of the device 1000, a window that displays real-time execution results of the associated applications. The window that displays real-time execution results of the associated applications may include a plurality of sub-windows. Also, each of the sub-windows may display an execution result with respect to a partial area selected from a whole area of an executed screen of the associated application.

FIG. 2 is a flowchart of a method of executing an associated application related to an interest object and displaying a result of executing the associated application, according to an exemplary embodiment.

In operation S200, the device 1000 displays an interest object on a screen of the device 1000. The interest object may be previously generated by the device 1000, and an associated application and metadata that are related to the interest object may be previously set.

The interest object may include at least one of text, an icon, and an image. For example, if the interest object is used to provide information about a location ‘Paris’ to a user, the interest object may be an icon related to location information, a picture of Paris, and a text “Paris”.

The interest object may be displayed on at least one of a lock screen, a home screen, and an application screen of the device 1000. In this case, the device 1000 may previously set on which of the lock screen, the home screen, and the application screen the interest object will be displayed. Also, the device 1000 may move the interest object between the lock screen, the home screen, and the application screen.

In operation S210, in response to selection of the interest object, the device 1000 obtains metadata related to the interest object. The device 1000 may previously set metadata items related to the interest object. The metadata related to the interest object may be updated according to a preset period.

When the interest object is selected, the device 1000 may check the metadata items related to the interest object, and may collect real-time values of the metadata. In this case, the metadata may be a plurality of pieces of data about the device 1000 and a current situation of the device 1000. For example, the metadata may include, but is not limited to, a plurality of pieces of data indicating a location of the device 1000, an application executed in the device 1000, a schedule of the user of the device 1000, a temperature, and a time.

In case the category of the interest object indicates ‘People’, metadata items related to the interest object may include ‘User’, ‘Phone’, and ‘e-mail’. Also, the device 1000 may obtain, as a metadata value of the metadata item ‘User’, a name of another user, and a social networking service identification (SNS ID) of the other user. Also, the device 1000 may obtain a phone number of the other user, as a metadata value of the metadata item ‘Phone’.

In case the category of the interest object indicates ‘Location’, a metadata item related to the interest object may include ‘Location’. In this case, the device 1000 may obtain a global positioning system (GPS) value of a current location of the device 1000, as a metadata value of the metadata item ‘Location’.

However, one or more exemplary embodiments are not limited thereto, and the metadata related to the interest object may not be collected in real-time. For example, the metadata related to the interest object may be a fixed value that was previously input by the user.

Regardless whether the interest object is selected, the device 1000 may update the metadata according to a preset period. In this case, the device 1000 may execute a function of collecting the metadata in a background of the device 1000. Also, when an interest object is generated, a function of collecting metadata related to the interest object may be automatically activated.

In operation S220, the device 1000 determines an application that matches the interest object. When the device 1000 generates the interest object, the device 1000 may associate the application and the interest object. Alternatively, once the interest object is selected, the device 1000 may determine the associated application that matches the interest object.

The associated application may automatically match the interest object, based on at least one of a category of the interest object, metadata items related to the interest object, and the metadata. For example, in case the category of the interest object indicates ‘People’, and the metadata items related to the interest object correspond to ‘User’ and ‘Phone’, a phonebook application, a messenger application, and an SNS application may be determined to match the interest object. As another example, in case the category of the interest object indicates ‘People’, and the metadata item related to the interest object corresponds to ‘e-mail’, an e-mail application may be determined to match the interest object.

The associated application may match the interest object, based on a user input. If the device 1000 generates the interest object, the device 1000 may display a list of associated applications to be selected by the user, and may match the interest object with at least one application that is selected by the user. In this case, the list of the associated applications may include titles of the associated applications recommended by the device 1000, based on the category of the interest object, the metadata item related to the interest object, and the metadata.

In operation S230, the device 1000 executes the associated application determined in operation S220, by using the metadata. The device 1000 may execute the associated application determined in operation S220, by using the metadata as an input value to the application. For example, if the metadata of the interest object corresponds to “010-1234-5678”, and the associated application related to the interest object include the phonebook application and the messenger application, and the device 1000 may execute the phonebook application and the messenger application and may input the metadata “010-1234-5678” to the phonebook application and the messenger application. Also, the device 1000 may search for content information in the associated application, by using the metadata as the input value to the application. Also, the device 1000 may search for a function menu of the associated application, by using the metadata as the input value.

Also, at least one function from among functions of the associated application may be preset to be executed according to in response to selection of the interest object. In this case, the device 1000 may execute only the at least one preset function of the associated application.

In operation S240, the device 1000 displays a window indicating a result of executing the associated application. The device 1000 may execute a plurality of associated applications and may display, on a screen of the device 1000, a window including a plurality of sub-windows that indicate results of executing the plurality of associated applications, respectively. For example, if the associated applications related to the interest object correspond to the phonebook application and the messenger application, the device 1000 may execute the phonebook application and the messenger application, and may display a window including sub-windows indicating results of executing the phonebook application and the messenger application, respectively.

Also, at least one function from among the functions of the associated application may be preset to be executed according to selection of the interest object. In this case, the device 1000 may generate a sub-window indicating result of executing the at least one preset function of the associated application.

Sizes of the sub-window and the window may be adjusted according to the number of associated applications, and an amount of data included in the execution result of the associated application. Alternatively, the sizes of the sub-window and the window may be adjusted based on a drag input by the user.

The execution result of the associated application may include data executed in the device 1000, data received from another device via a network, and data collected through the World Wide Web or Internet (hereinafter, the web).

FIG. 3 illustrates an example of a table with respect to metadata and an associated application that are related to an interest object.

Referring to FIG. 3, the table including information about the metadata and the associated application that are related to the interest object may include an interest object field 30, a category field 32, a metadata item field 34, a metadata field 36, and an associated application field 38.

In the interest object field 30, ID values of interest objects may be recorded. Also, in the interest object field 30, a plurality of pieces of link information used to retrieve the interest objects from a memory may be recorded.

In the category field 32, a category of an interest object may be recorded. The category of the interest object may include, but is not limited to, ‘People’, ‘Location’, ‘Media’, and ‘Search’.

In the metadata item field 34, metadata items related to the interest object may be recorded. For example, if the category of the interest object indicates ‘People’, the metadata item related to the interest object may include ‘User’, ‘Phone’, and ‘e-mail’. As another example, if the category of the interest object indicates ‘Location’, the metadata item of the metadata related to the interest object may include ‘location’. As another example, if the category of the interest object indicates ‘Media’, the metadata item related to the interest object may include ‘Music’ and ‘Movie’. As another example, if the category of the interest object indicates ‘Search’, the metadata item related to the interest object may include ‘News’, ‘Books’, and ‘Shopping’.

In the metadata field 36, a plurality of pieces of metadata according to the metadata items, which are obtained by the device 1000, may be recorded. For example, if the metadata item indicates ‘User’, the metadata may include a name and an SNS ID of another user. As another example, if the metadata item corresponds to ‘Phone’, the metadata may include a phone number of the other user. As another example, if the metadata item corresponds to ‘e-mail’, the metadata may include an e-mail address of the other user.

If the metadata item corresponds to ‘location’, the metadata may include an area name and a GPS value indicating a location of the device 1000. If the metadata item corresponds to ‘Music’, the metadata may include a song title and an artist's name.

If the metadata item corresponds to ‘News’, ‘Books’, or ‘Shopping’, the metadata may include a predetermined keyword value.

One or more values of the metadata recorded in the metadata field 36 may be fixed values that are preset by the user. However, the exemplary embodiments are not limited thereto, and the values of the metadata recorded in the metadata field 36 may be obtained in real-time by the device 1000. For example, if the category of the interest object indicates ‘People’, the device 1000 may record a name, an SNS ID, a phone number, and an e-mail address of another user who the user frequently contacts in the metadata field 36. As another example, if the category of the interest object indicates ‘Location’, the device 1000 may obtain in real-time a GPS value indicating a current location of the device 1000, and may record the GPS value in the metadata field 36.

As another example, if the category of the interest object indicates ‘Media’, the device 1000 may determine music or a movie to be recommended to the user, based on information about music or a movie that the user frequently or recently reproduces. The device 1000 may record metadata about the determined music and movie to be recommended, in the metadata field 36. In this case, the information about the music or the movie that the user frequently or recently reproduces may include information about a genre, a director, actors or actresses, etc. of the music or the movie, and context information (e.g., a location, a temperature, a time, etc.) in which the user reproduces the music or the movie.

If the category of the interest object indicates ‘Search’, the device 1000 may record a keyword about a user's recent interest in the metadata field 36. In this case, the keyword to be recorded in the metadata field 36 may be determined based on a call history of the user, a search history of the user, a content usage history of the user or a shopping history of the user. The keyword may be input to the associated application (e.g., a search application, a web browser, a book application, a price-comparison application, etc.) and thus may be used by the device 1000 in searching predetermined information. Also, a category value of the keyword may be input to the associated application.

In the associated application field 38, a type or an ID value of the associated application corresponding to the interest object may be recorded. Also, in the associated application field 38, at least one of the category of the interest object, the metadata item of the interest object, and the metadata of the interest object, and the associated application related to the interest object may be recorded.

For example, if the category of the interest object indicates ‘People’, and the metadata item of the interest object indicates ‘User’ or ‘Phone’, a phonebook application, a messenger application, an SNS application, and a content sharing application may be recorded in the associated application field 38. If the category of the interest object indicates ‘Location’, an application using location information may be recorded in the associated application field 38. For example, a weather application, a clock application, a map application, and a navigation application may be recorded in the associated application field 38.

The associated application related to the interest object may be set by the user, but one or more exemplary embodiments are not limited thereto. The device 1000 may recommend the associated application, based on the category of the interest object, the metadata item of the interest object, and the metadata of the interest object. Alternatively, the device 1000 may select some of associated applications recommended by the user.

At least one function from among the functions of the associated application may match the interest object. For example, from among functions of the messenger application, a function for chatting with a device of a particular user may match the interest object. In this case, a chat window for chatting with the particular user may be included, as an execution result of the messenger application, in a window.

For example, a partial area from an executed screen of the associated application, which is selected by the user, may match the interest object. In this case, an execution result displayed on the partial area selected by the user may be included, as an execution result of the associated application, in a window.

FIG. 4 illustrates an interest object 40 and associated applications 42, 44, 46, and 48 related to the interest object 40, according to an exemplary embodiment.

Referring to FIG. 4, the interest object 40 may match the associated applications 42, 44, 46, and 48. The interest object 40 may be displayed on a screen of the device 1000 to help a user obtain information related to a location ‘Paris’.

A category of the interest object 40 may indicate ‘Location’, and the location ‘Paris’ and ‘a GPS value of Paris’ correspond to metadata related to the interest object 40. For example, when the interest object 40 is selected, the device 1000 may execute a map application 44, and may mark a location of Paris on a map, which is provided by the map application 44, by using the GPS value of Paris as an input value.

As another example, when the interest object 40 is selected, the device 1000 may execute a music application 46, may scan music related to Paris by using Paris as an input value to a search application for finding the related music, and then may reproduce the music.

FIG. 5 is a flowchart of a method of generating an interest object, the method performed by the device 1000, according to an exemplary embodiment.

In operation S500, the device 1000 selects an associated application to be matched with the interest object. The device 1000 may select the associated application to be matched with the interest object, based on an executed screen of an application or a user input to the application. For example, when a user touches the icon of the application over a preset period of time, a menu for selecting the associated application may be displayed, and based on a user input to the menu, the device 1000 may set the application as the associated application. As another example, when the user selects a category of the interest object, one or more applications related to the selected category may be recommended by the device 1000, and based on a user input for selecting at least one application from among the one or more recommended applications, the device 1000 may set the associated application. However, one or more exemplary embodiments are not limited thereto, and the device 1000 may provide, to the user, various user interfaces for setting the associated application.

In operation S510, the device 1000 selects one or more metadata items to be matched with the interest object. In response to selection of the associated application, the device 1000 may display a selection menu for selecting metadata items related to the associated application. Based on a user input to the selection menu, the device 1000 may select a predetermined metadata item. For example, when the user selects the category of the interest object, one or more metadata items related to the selected category may be recommended by the device 1000, and based on a user input, the device 1000 may select at least one metadata item from among the one or more recommended metadata items. However, one or more exemplary embodiments are not limited thereto, and the device 1000 may provide, to the user, various user interfaces for setting the metadata items.

In operation S520, the device 1000 generates the interest object that matches the selected associated application and the selected metadata item. The device 1000 may generate the interest object, and may match the interest object with the selected associated application and the selected metadata item.

The interest object may include the icon of at least one associated application related to the interest object. Also, the interest object may include the text indicating at least one of the category of the interest object, the metadata item, and metadata related to the interest object. Also, the interest object may include the image indicating a partial area of an executed screen of the associated application that is executed by using the metadata as an input value. For example, the device 1000 may match the interest object with a phonebook application and a category ‘People’.

Also, the device 1000 may match the interest object with the metadata related to the interest object. For example, if the interest object is related to communication with another user “Amanda”, the device 1000 may match the interest object with “Amanda” that is a name of the other user. As another example, if the interest object is related to communication with the other user “Amanda”, the device 1000 may match the interest object with a phonebook application, a messenger application, and an SNS application.

The device 1000 may store the interest object in a memory of the device 1000. However, one or more exemplary embodiments are not limited thereto, and the device 1000 may store the interest object in another device or an external server. For example, the device 1000 may store the interest object in a service-providing server (not shown), and may receive a service related to the interest object from the service-providing server.

In operation S530, the device 1000 displays the interest object on the screen.
